METEO 003 Lab 10 due Nov 21 Albedo Review • reflectivity of a surface (sunlight) • What geographical features can be seen on visible image? • Look at Figure 16.29 Question 1a,b Albedo Review • Might be easier to tell where there is clear sky on infrared image in this case. • What geographical features can be seen on infrared image, if any? Could they be seen if it’s cloudy? • Look at Figure 16.29 Question 1a,b Precipitation Types • Rain – Precipitation in the form of liquid water drops • Snow – Precipitation comprised of white ice crystals, primarily in complex branch hexagonal form • Freezing Rain – Rain that falls in liquid form but freezes upon impact • Sleet – A type of precipitation consisting of transparent pellets of ice Question 3 Precipitation Types Question 3 Lake Effect Data Analysis • General rule: the shallower the lake, the sooner it will freeze • Interpret the graphs/tables, they contain all the answers • *No calculation needed for part a Question 6a,b,c,d Map Analysis • Lapse rate = change in temperature change in height • Surface air temperatures (over water) will be similar to (assume the same as) surface water temperatures • Remember surface winds cross isobars at about a 30 degree angle towards lower pressure • Look at Figure 16.27 Question 7a,b,c Air Mass Types • • • • Continental: dry Maritime: moist Polar: cold/cool Tropical: hot/warm • Combinations: mT, mP, cT, cP Question 8a,b,c,e Wind Orientation and Lake Effect • Wind direction parallel to major lake axis = single major band of lake effect snow • Wind direction perpendicular to major lake axis = multiple discrete bands of lake effect snow Question 8a,b,c,e Temperature Anomalies • Positive: warmer than average • Negative: colder than average Question 9a,b Wind Chill • The perceived decrease in air temperature felt by the body on exposed skin due to the flow of air • Increased winds speed, decreased temperature, or a combination of both = lower wind chill and less time needed for frostbite Question 11a Question 11a Lab 10 due Nov 21 • Chapter 16 – 1a,b – 3 – know precipitation types and conditions needed for each – 6a,b,c,d – shallow lakes freeze earlier – 7a,b,c – convert K to C for surface temp – 8a,b,c,e – not as much friction over lake – 9a,b – 11a
